Paul Julius Gottlieb Nipkow (22 August 1860 – 24 August 1940) was a German technician and inventor. He invented the Nipkow disk, one of the first successful technologies for television transmission. Hundreds of stations experimented with television broadcasting using the Nipkow system in the 1920s and 1930s, until it was superseded by all-electronic systems in the 1940s.
John Logie Baird FRSE (14 August 1888 – 14 June 1946) was a Scottish engineer, innovator and inventor of the world's first mechanical television; the first publicly demonstrated colour television system; and the first purely electronic colour television picture tube. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.
Vladimir Kosmich Zworykin (July 29 [O.S. July 17] 1888 – July 29, 1982) was a Russian-American inventor, engineer, and pioneer of television technology. Zworykin invented a television transmitting and receiving system employing cathode ray tubes. He played a role in the practical development of television from the early thirties, including charge storage-type tubes, infrared image tubes and the electron microscope.
